A. SELECTED EMBODIMENTS OF LIQUID DISPENSING HAIRBRUSH SYSTEMS AND ASSOCIATED DEVICES

FIGS. 1A-1C are side, front, and rear views, respectively, of a liquid dispensing hairbrush system 100 configured in accordance with an embodiment of the present technology, and FIG. 1D is a cross sectional view taken along line 1D-1D in FIG. 1B. Referring to FIGS. 1A-1C together, the hairbrush system 100 (which can also be referred to as a “hairbrush 100”) includes a brush body 103, a bristle support layer 110, and a removable liquid container 130. The brush body 103 includes a brush head 104 and a handle 106. In some embodiments, the brush body 103 can additionally include one or more features 107 and/or 117 (e.g., recesses, ridges, protrusions, notches, etc.) that are aesthetic and/or functional by, for example, providing a gripping surface to the handle 106. In the illustrated embodiment, the brush body 103 is a unitary piece of polymer material (e.g., plastic) having a front side 101 (FIGS. 1A and 1B) and a back side 102 (FIG. 1C). In other embodiments, the brush body 103 and/or components of the brush body 103 can be made of a different material (e.g., a metal, composite, glass, wood, rubber, etc.). The brush body 103 can be formed by injection molding, and/or the brush body 103 can be cast, machined, carved, 3D-printed, or otherwise manufactured.

As shown in FIGS. 1C and 1D, the back side 102 of the brush head 104 can optionally include an aperture 105. In these embodiments, the hairbrush system 100 can include a bladder 115 attached to an inside surface 148 (FIG. 1D) of the back side 102 of the brush head 104. The bladder 115 can be sealably glued to the inside surface 148 using an adhesive. For example, the bladder 115 can be glued to the inside surface 148 at points 109 (FIG. 1D) along and/or near the periphery of the bladder 115. The bladder 115 is sized and shaped to (i) fit within the brush head 104 and (ii) to cover and seal off the aperture 105 such that liquid that enters a chamber 160 (FIG. 1D) in the brush head 104 cannot leak out via the aperture 105. In some embodiments, the bladder 115 can be made of a flexible polymer material (e.g., rubber, plastic, etc.). As described in greater detail below, the aperture 105 can be sized and shaped such that a user can press an exposed portion 116 of the bladder 115 through the aperture 105 and toward the front side 101 of the brush body 103 to increase pressure on liquid in the chamber 160 and to force the liquid through apertures in the bristle support layer 110 and onto the user's hair. In some embodiments, the bladder 115 can be transparent, so that a user can view whether there is liquid within the chamber 160 of the brush head 104 via the aperture 105.

Referring to FIGS. 1A, 1B, and 1D together, in the illustrated embodiment, the bristle support layer 110 is a unitary piece of polymer material (e.g., rubber, plastic, etc.). A plurality of bristles 112 extend outwardly from a front side 113 of the bristle support layer 110. The bristles 112 can be made from a flexible or rigid polymer material (e.g., plastic, rubber, etc.), fiberglass, metal(s), and/or other suitable materials known in the art. The bristle support layer 110 can include a plurality of apertures 114 between the bristles that pass from the front side 113 to a back side 146 (FIG. 1D) of the bristle support layer 110. Although the bristle support layer 110 is shown with a plurality of apertures 114 in the illustrated embodiment, in other embodiments, the bristle support layer 110 can include a greater or lesser (e.g., one, two, three, etc.) number of apertures 114 and/or can include the apertures 114 in different patterns and/or spacings than shown.

Referring to FIG. 1D, the bristle support layer 110 can be secured to the brush head 104 and/or to the bladder 115 using an adhesive and/or another method (e.g., using a heat sealer). More specifically, the periphery of the bristle support layer 110 can be bonded (e.g., glued) with an adhesive or otherwise sealably attached and secured to an inside lip on surface 147 of the brush body 103 and/or to the bladder 115 to create a water-tight seal along the periphery edges of the bristle support layer 110. The bristle support layer 110 is sized and shaped to fit within an opening 126 in the brush head 104. For example, the bristle support layer 110 can be flexed and/or folded to fit within the brush head 104 between the front side 101 and the back side 102 of the brush body 103.

FIG. 2 is a cross-sectional view along line 2-2 in FIG. 1B of the brush head 104 configured in accordance with an alternative embodiment of the present technology. In the illustrated embodiment, the brush body 103 can include an edge member 218. The edge member 218 can engage (e.g., snap, clip, clamp, etc.) with the brush head 104 (e.g., along dashed line 108 (FIGS. 1A and 1B)) to (i) secure the bristle support layer 110 and/or the bladder 115 to the brush head 104 by clamping (e.g., pinching) the bristle support layer 110 and/or the bladder 115 between the edge member 218 and the perimeter edge of the brush head 104 and (ii) form a watertight seal along the periphery edges of the bristle support layer 110 and/or the bladder 115. In some embodiments, an adhesive can be used (i) to secure the bristle support layer 110, the bladder 115, the edge member 218, and/or the brush head 104 together and/or (ii) to form and/or reinforce the watertight seal. In other embodiments, the bristle support layer 110 and/or the bladder 115 can be removable (i) so that a user can clean the bristle support layer 110, the bladder 115, and/or the brush head 104 and/or (ii) so that a user can replace the bristle support layer 110 and/or the bladder 115.

As described in greater detail below, the brush head 104, the bristle support layer 110, and/or the bladder 115 illustrated in FIGS. 1A-2 define the chamber 160 (FIGS. 1D and 2) of the brush head 104. The chamber 160 receives fluid from the liquid container 130 when the liquid container 130 is fully installed within the handle 106. In some embodiments, the system 100 can include a sponge (not shown) within the chamber 160 to facilitate distribution of liquid that enters the chamber 160 to the plurality of apertures 114 in the bristle support layer 110. After liquid enters the chamber 160, a user can force liquid out of the chamber 160 via the plurality of apertures 114 by applying pressure to the bristle support layer 110 and/or to the bristles 112. For example, the bristle support layer 110 can be compressed (via, e.g., pressure applied to the bristles 112), which forces liquid out of the plurality of apertures 114. Additionally or alternatively, a user can push on the exposed portion 116 of the bladder 115 through the aperture 105 to increase pressure applied to the liquid, forcing the liquid out of the plurality of apertures 114 in the bristle support layer 110.

FIG. 3 is an isometric view of the handle 106 configured in accordance with an embodiment of the present technology. In the illustrated embodiment, the handle 106 includes a cavity 323 having an opening 329 with a width W1 and a height H1. The handle 106 additionally includes inwardly protruding ridges 327 that extend longitudinally along the handle 106. Although the handle 106 includes two ridges 327 in the illustrated embodiment, in other embodiments, the handle 106 can include a greater (e.g., three, four, etc.) or a fewer (e.g., one) number of ridges 327 and/or can include ridges 327 at other locations about a perimeter of the cavity 323.

As described in greater detail below, the ridges 327 are configured to align and/or register with corresponding grooves or recesses on the liquid container 130. In this manner, the handle 106 can be configured to receive liquid containers 130 having a particular size, shape, and/or orientation corresponding to the ridges 327 in the handle 106 and to the internal dimensions of the cavity 323. Thus, the ridges 327 and the dimensions of the opening 329 can limit use of the brush body 103 to liquid containers 130 of a particular brand, manufacturer, vendor, liquid, etc. Additionally or alternatively, the ridges 327 can align the liquid container 130 in a specific orientation within the handle 106 and prevent the liquid container 130 from rotating within the handle 106.

Although not shown, in some embodiments, the handle 106 can include one or more lips and/or one or more recesses that extend around at least a portion of the cavity 323 (e.g., near the opening 329 and/or at another location within the cavity 323). The lip(s) and/or recess(es) can engage corresponding features of the liquid container 130 to help retain the liquid container 130 within the cavity 323 of the handle 106. Additionally or alternatively, the lip(s) and/or recesses can be configured to limit use of the brush body 103 to liquid containers 130 of a particular size, shape, and/or manufacturer.

FIG. 4A is a side view and FIG. 4B is a front view of the liquid container 130 configured in accordance with an embodiment of the present technology. Referring to FIGS. 4A and 4B together, the liquid container 130 includes a neck 431, a body 432, and a base 433 that define an interior chamber 450 configured to hold a liquid (water; hair gel; mousse; hair mask; shampoo; conditioner; tea tree oil; lotion; other hair, fur, and/or fiber liquid products; and/or other liquids).

The neck 431 of the liquid container 130 is generally circular and includes an annular recess 435 configured to receive an O-ring 120 (partially shown). In other embodiments, the neck 431 can have more than one recess 435, each configured to receive an O-ring 120. In still other embodiments, the neck 431 can include threads configured to engage complimentary threads (not shown) within the handle 106 in addition to or in lieu of the recess 435. In the illustrated embodiment, the neck 431 defines a mouth or opening 434 of the chamber 450.

As shown in FIG. 4B, the body 432 can have sides 437 and 438 that are generally curved outwardly with respect to a longitudinal axis L of the liquid container 130 such that the body 432 has a maximum width W2. In other embodiments, the side(s) 437 and 438 can be straight and/or have a different contour. As best shown in FIG. 4A, the body 432 can have a height H2 between a front side 439 and a back side 440. In this embodiment, the width W2 and the height H2 generally correspond to (but are slightly less than) the width W1 and the height H1 of the opening 329 of the cavity 323 in the handle 106 such that the mouth 331 and the body 332 of the liquid container 130 can fit within the cavity 323 of the handle 106.

The base 433 has a height H3 (FIG. 4A) and a width W3 (FIG. 4B) near where the body 432 meets the base 433. In this embodiment, the height H3 and the width W3 are larger than the height H1 and the width W1, of the opening 329 in the handle 106 (FIG. 2) so that the liquid container 130 includes a step surface 441 that is configured to abut against the handle 106 at the opening 329 (FIG. 2) to prevent the liquid container 130 from being inserted into the handle 106 beyond the surface 441. In these and other embodiments, the base 433 is configured to remain external to the handle 106 and/or can be transparent to, for example, (i) provide a visual indication of how much liquid remains within the liquid container 130, and/or (ii) allow the user to push and/or to pull the liquid container 130 into and/or out of the handle 106 using the base 433. In these and still other embodiments, the base 433 can remain external to the handle 106 to display, for example, a label showing the user a brand and/or manufacturer of the liquid container 130 and/or a type of liquid in the liquid container 130.

Although the body 432 and the base 433 are shown with a generally rectangular cross-sectional shape, in other embodiments the body 432 and/or the base 433 of liquid container 130 can have different shapes (e.g., circular, triangular, etc.). In these and other embodiments, the body 432 and/or the base 433 can have different and/or varying dimensions (e.g., width W2, width W3, height H2, and/or height H3) in relation to the dimensions of the cavity 323 and/or in relation to one another. For example, the base 433 can be sized and shaped such that the base 433 can extend within the cavity 323.

As best shown in FIG. 4B, the body 432 includes a recess 451 (e.g., a groove or channel) on the front side 439 and a corresponding recess (not shown) on the back side 440 that extend parallel to the longitudinal axis L from proximate the base 433 to proximate the neck 431. The recesses 451 are configured to align with and receive the ridges 327 (FIG. 2) when the container 130 is inserted into the cavity 323 in the handle 106. In other embodiments, the recesses 451 can extend along the neck 431 and/or the base 433 in addition to or in lieu of the body 432. In these and other embodiments, the container 130 can include recesses 451 at other locations on the liquid container 130, such as on the sides 437-440. In these and other embodiments, the liquid container 130 can include ridges (not shown) in addition to or in lieu of the recesses 451.

In some embodiments, the liquid container 130 can include additional features to facilitate forcing liquid out of the container chamber 450. For example, FIGS. 5 and 6 are partially cut-away front views of liquid containers 530 and 630, respectively, configured in accordance with embodiments of the present technology. Referring first to FIG. 5, the liquid container 530 is generally similar to the liquid container 130 described in detail above with the exception that (i) the body 432 has a constant cross section and (ii) the liquid container 530 includes a plunger 549 having a piston 547. The piston 547 can be configured to slide along the interior surfaces the liquid container 530 and can include an O-ring 520 to inhibit liquid found at the piston from moving beneath the piston 547. As shown by arrows illustrated in FIG. 5, the plunger 549 can be actuated toward (e.g., pushed into) the liquid container 530 to force liquid forward of the plunger out of the chamber 450 through the mouth 434. In some embodiments, the plunger 549 can be actuated (e.g., pulled) away from the liquid container 530 to draw liquid into the chamber 450 for use.

Referring next to FIG. 6, the liquid container 630 is generally similar to the liquid containers 130 and 530 described above with the exception that (i) the body 432 has a constant cross section and (ii) the liquid container 630 includes a knob 652 operably coupled to a worm screw 653 that drives a piston 657. The piston 657 slide along interior surfaces of the sides 437-440 of the liquid container 630 and can include one or more O-rings 620 such that liquid in the chamber 450 is inhibited from moving behind the piston 657. The worm screw 653 extends from the chamber 450 and the piston 657 to the knob 652 where it is fixedly attached to the knob 652. The worm screw 653 is threaded such that (i) when a user turns the knob 652 in one direction, the worm screw 653 drives the piston 657 toward the mouth 434 and (ii) when the user turns the knob 652 in the other direction, the worm screw 653 drives the piston 657 toward a base portion 656 (as shown by arrows illustrated in FIG. 6). As the worm screw 653 drives the piston 657 toward the mouth 434, the piston 657 forces liquid in the chamber 450 out of the mouth 434.

In other embodiments, the piston 547 and/or the piston 657 can be connected to a lever (not shown) that extends to an exterior of the liquid containers 530 and/or 630. The lever can be actuated such that liquid within the chamber 450 is forced out of the mouth 434. In other embodiments, the liquid containers 530 and/or 630 can include an air pump (not shown). The air pump can be actuated to force air into the chamber 450 (e.g., beneath a piston and/or beneath liquid within the chamber 450), such that the air forces liquid within the chamber 450 out of the mouth 434.

FIG. 7A is a partially exploded side view of the liquid dispensing hairbrush system 100 of FIGS. 1A-1D configured in accordance with an embodiment of the present technology. The annular recess 435 in the liquid container 130 is configured to receive the O-ring 120. The handle 106 of the brush body 103 is configured to receive the liquid container 130 in the cavity 323 via the opening 329 and the container is pushed forward until the O-ring 120 is received in an annular recess found in the handle, as discussed below.

FIGS. 7B and 7C are partial cross-sectional side views along lines 7B-7B and 7C-7C, respectively, in FIG. 1B of the brush body 103. For clarity, a side view of the liquid container 130 is illustrated in FIGS. 7B and 7C rather than a cross-sectional side view. Referring to FIGS. 7B and 7C together, the liquid container 130 can be inserted into the cavity 323 in the handle 106. As shown, the brush body 103 includes an annular recess or seat 745 (FIG. 7B) configured to receive the O-ring 120. When the O-ring 120 is positioned with the seat 745, the O-ring 120 creates (i) a vacuum seal between the chamber 450 of the liquid container 130 and the chamber 160 of the brush head 104 and/or (ii) a watertight seal between the chambers 450 and 160 and the cavity 323.

As best shown in FIG. 7C, the chamber 160 is configured to be in fluid communication with the chamber 450 when the liquid container is inserted into the cavity 323 of the handle 106. The stepped surface 441 of the liquid container 130 abuts against the handle 106 at the opening 329 and prevents the liquid container 130 from being inserted too far into the brush body 103. In some embodiments, the O-ring 120 and the seat 745 can retain the liquid container 130 in the cavity 323.

Although the brush body 103 is configured to receive the liquid container 130 in the cavity 323 of the handle 106, hairbrush systems configured in accordance with other embodiments can have different configurations. For example, the handle 106 in other embodiments can include multiple components, such as a front side (not shown) and a back side (not shown). In these embodiments, the front side can be at least partially detached from the back side to permit installation of the liquid container 130. In an assembled state, the front side of the handle 106 can be clipped, snapped, and/or otherwise connected to the back side of the handle 106 about the liquid container 130. In other embodiments, the liquid container 130 can be attached to the back side 102 of the brush head 104 and configured to introduce liquid into the chamber 160 of the brush head 104 via the aperture 105 and/or one or more other apertures (not shown) in the back side 102 of the brush head 104.

Referring again to FIGS. 7B and 7C together, at the edge of the seat 745 nearest the brush head 104 (i) the bristle support layer 110 is attached to the inside surface 147 of the brush head 104 and (ii) the bladder 115 is attached to the inside surface 148 of the brush head 104. As discussed above, the bristle support layer 110 and/or the bladder 115 can be attached to the surfaces 147 and/or 148 using an adhesive (not shown) and/or one or more other attachment methods (e.g., along the periphery of the bristle support layer 110 and/or the bladder 115). In the illustrated embodiment, the bristle support layer 110 and the bladder 115 are attached to one another all the way around the brush body 103 proximate the edge of the seat 745 to form an opening 765 through which liquid can enter into and/or exit out of the chamber 160. In other embodiments, the bristle support layer 110 and the bladder 115 are not attached to one another at the edge of the seat 745 but are attached to the surfaces 147 and 148 such that the bristle support layer 110 and the bladder 115 form the opening 765 with a portion of the surface 147 and/or of the surface 148 of the brush body 103. In still other embodiments, the bristle support layer 110 and/or the bladder 115 can be attached to the brush body 103 and/or to one another at different locations, such as within the cavity 323 in the handle 106 or at a point closer to the aperture 105 in the brush head 104 from the edge of the seat 745.

In operation, the liquid container 130 is configured to transfer liquid from the chamber 450 to the chamber 160 of the brush head 104 at a suitable rate as the user brushes their hair. For example, the liquid container 130 can transfer liquid to the chamber 160 using gravity (e.g., when the hairbrush system 100 is tilted). In some embodiments, the liquid container 130 can transfer liquid to the chamber 160 using suction that is created when, for example, the bristle support layer 110 is decompresses and/or when the bladder 115 expands after a user compresses the bristle support layer 110 and/or presses on the bladder 115 through the aperture 105 in the back side 102 of the brush head 104. In other embodiments, the liquid container 130 can transfer liquid to the chamber 160 using capillary action (e.g., via a tube (not shown) that extends from the chamber 450 to a sponge in the brush head 104). In some embodiments, a portion (e.g., the body 432 and/or the base 433) of the liquid container 130 and/or a portion of the brush body 103 (e.g., the handle 106 and/or the back of the brush head 104) can be compressible such that liquid is transferred from the chamber 450 the brush head 104 when the liquid container 130 is compressed. In still other embodiments, a user can transfer liquid from the chamber 450 to the chamber 160 by actuating mechanical components such as the plunger 549, the knob 552, a lever, and/or an air pump.

After liquid enters the chamber 160 in the brush head 104, a user can force the liquid out of the chamber 160 and onto the bristles 112. For example, a user can apply pressure to the bristle support layer 110 (e.g., by applying pressure to the bristles 112), which can compress the bristle support layer 110 and drive liquid in the chamber 160 through the apertures 114 in the bristle support layer 110. In some embodiments, the hairbrush system 100 can be configured to release more liquid out of the chamber 160 as a user increases and/or reapplies pressure to the bristle support layer 110. In these and other embodiments, a user can press the portion 116 of the bladder 115 exposed through the aperture 105 in the back side 102 of the brush head 104 toward the front side 101 of the brush body 103 using, for example, their thumb 770 to force liquid in the chamber 160 through the apertures 114. In these and other embodiments, liquid can be forced out of the chamber 160 by, for example, actuating the mechanical components of the liquid container 130 and/or compressing the liquid container 130. Once a user transfers liquid to the front side 113 of the bristle support layer 110, the user can apply the liquid to and/or brush the liquid through their hair (e.g., using the bristles 112).

FIG. 8 is an isometric view illustrating a liquid dispensing hairbrush system 800 configured in accordance with another embodiment of the present technology. The system includes a brush body 803, a bristle support layer 810, a liquid container 830, a sponge 884, and a tube 886. The brush body 803 includes a brush head 804, a handle 806, and an edge member 881. The edge member 881 can engage (e.g., snap, clip, clamp, etc.) with the brush head 804 at a front side 801 of the brush head 804 to secure the bristle support layer 810 between the edge member 881 and the brush head 804 and to form a watertight seal along the periphery edges of the bristle support layer 810 (e.g., in a manner similar to the edge member 218 and the brush head 104 illustrated in FIG. 2). In some embodiments, an adhesive can be used to secure the bristle support layer 810, the edge member 881, and/or the brush head 804 together and/or (ii) to form and/or reinforce the watertight seal. In these and other embodiments, the edge member 881 and the brush head 804 can clamp at least a portion of the handle 806 to secure the handle 806 between the edge member 881 and the brush head 804.

In the illustrated embodiment, the bristle support layer 810 is a unitary piece of polymer material (e.g., rubber, plastic, etc.) and is similar to the bristle support layer 110 (FIG. 1). For example, the bristle support layer 810 includes one or more apertures 814 passing from a front side 813 to a back side 846 of the bristle support layer 810. A plurality of bristles 812 extend outwardly from the front side 813 of the bristle support layer 810 about the apertures 814. The bristle support layer 810 can be folded and/or flexed to fit between the edge member 881 and the brush head 804. In some embodiments, the bristle support layer 810 can be removable (i) so that a user can clean the bristle support layer 810 and/or the brush head 804 and/or (ii) so that a user can replace the bristle support layer 810. In the illustrated embodiment, the bristle support layer 810 and the brush head 804 define a chamber 860 in the brush body 103.

The sponge 884 is positioned within the chamber 860. In some embodiments, the sponge 884 can be attached to an interior surface 848 of the brush body 803 (e.g., using an adhesive and/or another attachment method). In these and other embodiments, the sponge 884 can be attached to the back side 846 of the bristle support layer 810, to the edge member 881, and/or to the handle 106. As described in greater detail below, the sponge 884 is configured to receive liquid from the liquid container 830 and to absorb and distribute the liquid throughout the chamber 860 (e.g., to the apertures 814 in the bristle support layer 810). In some embodiments, the sponge 884 can be removable so that a user can clean and/or replace it.

In the illustrated embodiment, the liquid container 830 is an extension of the handle 106. As shown, the liquid container 830 includes a neck 831, a body 832, and a base 833 that each have a generally circular cross section. The neck 831 is connected to the tube 886, which extends between the neck 831 and the sponge 884. The body 832 defines an interior chamber 850 that is configured to hold a liquid (e.g., water, hairspray, hair gel, mousse, hair mask, shampoo, conditioner, tea tree oil, lotion, and other hair, fur, and/or fiber liquid products). In these and other embodiments, the chamber 850 can be configured to hold other fluids and/or liquids.

As shown, the base 833 includes a bulb 897 attached to the base 833. The bulb 897 can be made of a polymer material (e.g., rubber, plastic, etc.). In the illustrated embodiment, the bulb 897 is configured to force fluid into the tube 886 when it is compressed by forcing fluid (e.g., liquid and/or air) into the body 832. In other embodiments, the base 833 can include an air pump (not shown) in lieu of the bulb 897. The air pump can be configured to operate in a generally similar manner as the bulb 897 except that the air pump is configured to draw air into the chamber 850 (e.g., via a valve) as it expands after being compressed. As a result, the air pump can force an increasing volume of air into the chamber 850 (e.g., through multiple compressions) until the liquid in the chamber 850 is depleted and/or exhausted. In these and other embodiments, the body 832 of the liquid container 830 can be compressed, which can force liquid into the sponge 884 via the tube 886. In these and still other embodiments, liquid from the chamber 850 can be transferred to the sponge 884 via capillary action and/or suction (e.g., after a user compresses the bristle support layer 810, as described in greater detail below).

In operation, a user can force liquid out of the chamber 860 and onto the bristles 812 via the apertures 814 in the bristle support layer 810. For example, a user can force liquid out of the chamber 860 by compressing the bulb 897, the air pump, and/or the liquid container 830. In these and other embodiments, a user can force liquid out of the apertures 114 by applying pressure to the bristle support layer 810 and/or to the sponge 884 (e.g., via the bristles 812). In these and still other embodiments, the brush head 804 of the brush head 804 can include an aperture (not shown) similar to the aperture 105 (FIG. 1C), for example, passing from a back side 802 of the brush head 804 and into the chamber 860 (e.g., beneath the sponge 884). In these embodiments, the hairbrush system 800 can include a bladder (not shown) beneath the sponge 884 and attached (e.g., glued) to the inside surface 848 of the brush head 804 along the periphery of the bladder 115 to prevent liquid from leaking out of the chamber 860 via the aperture in the brush head 804. A portion (not shown) of the bladder similar to the portion 116 (FIG. 1C) can be exposed through the aperture, and a user can press the portion to apply pressure to liquid in the chamber 860 and to force the liquid through the apertures 814 in the bristle support layer 810. Once a user transfers liquid to the front side 813 of the bristle support layer 810, the user can apply the liquid to and/or brush the liquid through their hair (e.g., using the bristles 812).
